MACHINE FOR O RNAMENTING GLASSWARE.

' SPECIFICATION forming part of Letters Patent No. 549,376, dated November 5, 1895.

Application filed February 26, I895. Serial No. 539,833. (No model.)

To all whom it may concern.-

Be it known that I, Or'ro FREDRIK LILJE- QVIST, asubject of the King of Sweden and Norway, residing at White Mills,in the county of Wayne and State of Pennsylvania,have invented certain new and useful Improvements in Machines for Ornamenting Glassware, of which the following is a specification.

My invention relates to machines for ornamenting glasswaresuch as drinking-glasses, tumblers, and the likeby forming straight and irregular bands around the peripheries thereof.

The invention appertains more particularly to the means for holding and operating the marking-tools and to the means for securing the glass to be ornamented during the marking operation. 7

It also includes the details of construction, as Will behereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, illustrating my invention, Figure 1 is a perspective view of the machine. Fig. 2 is a front elevation. Fig. 3 is a detail of one formof tool-holder. Fig. 4: is a detail of the preferred form of chuck. Fig. 5 is a detail of the marking-tool. Fig. 6 is a detail of another form of tool-holder and the tool. Figs. 7 and Sare views of the ornamented articles. Fig. 9 is a detail of another form of tool-holder.

In the drawings, A represents the base, carrying the vertical standards a a, adapted to be secured to a suitable bench or table. In the-upper part of the standards is j ournaled the shaft 1), which carries the driving-pulley b, to which motion is imparted by a belt (not shown) from any suitable source of power. A chuck 0, preferably of wood, is secured to the end of the shaft 1), and is provided with a series of longitudinal slits to permit it to be expanded to receive the article to be ornamented. The tumbler or drinking glass to be ornamented is fitted within this chuck, the end of the glass bearing against a shoulder 0 around the inner periphery thereof. A collar c is fitted on the outer periphery of the chuck and is adapted to be slipped up near the forward end thereof to contract the slitted portion and cause it to securely clamp the glass. This collar 0 is operated by rods 01, carrying segmental bearing-pieces 0 which engage an annular groove in the collar, the said rods passing loosely through openings provided in the vertical standards. As not all the tumblers or articles which it may be desired to engrave are round, it will be seen that if the collar be made of rigid material it will pinch the chuck down hard upon the glass and will tend to break an irregular article. In order to avoid this, the band or collar around the chuck may be made of thin flexible steel, preferably about an inch wide by about one thirty second of an inch in thickness, and the arms 0 are riveted to this band and extend backward to the main collar 0 This construction is clearly shown in Fig. 4:. It is found that in using this band the wood, which is softened by the water, will become worn or frayed. To obviate this, staples or dogs 0 of steel wire are placed in the sections of the chuck and form a bearing for the ring.

Collars O are secured to the rods d by thumb-screws, and between these collars and the vertical standard a are helical springs y, which surround the rods (Z and tend normally to force the collar 0 011 the forward part of the chuck, thus contracting the end of the same to clamp the article. A lever f is secured to boxing held loosely upon the shaft, and from this boxing the collars e extend to and engage with the rods d. One end of this lever is pivoted to a bar projecting horizontally from the standard a, theopposite end being provided with a handle to be grasped by the operator, whereby the rods may be drawn back against the pressure of the springs to unclamp the chuck. The drivingpulley b is provided with a rigidly-attached disk 17*, having a groove in its periphery in which rest two segmental plates b which are connected to the rods (1, so that as these are moved to clamp the article upon the chuck the driving-pulley will be moved upon the shaft, and as the shaft is tapered at this point the pulley will engage with the enlarged part of the shaft to drive the same, thus forming a friction-clutch. I do not, however, limit myself to this particular form of clutch, as some other might be substituted therefor.

Therear end of the shaft b carries a beveled gear 2, that meshes with a gear 3, journaled on a vertical spindle 4, which imparts motion through the beveled gear 5 to the horizontally-journaled gears (i and 7. The disks 8, secured on each end of the horizontal shaft, are provided with pins 9, eccentrieally secured thereto. These pins project through the vertically-slotted heads of the rods 72, extending through openings in the standards a a, and thus reciprocate the rods. The rods are detachably connected to the plates L, which slide upon the tracks is, fastened to the base A. Projecting upwardly from these plates are the bearings Z, in which the shafts of the casing lare journaled. The rodsm, having the clamps 11 secured on the end thereof, are held in the casings and can be adjusted and held by means of thumb-screws extending through the bearings Z and engaging with the shafts of the casings.

The spring-arms P are adjustably held at one end by the clamps n and carry at their opposite ends the frames '1 for holding the rubbing or engraving tools. These frames consist, in one instance, of the blocks or projections 1' secured to the spring-arms, and one of these blocks or projections carries a pointed stud r, projectinginwardly, while the other has a threaded opening through which a pointed screw 2' extends. A marking-block 0-, of steel, having an indentation in ea eh end, is carried by this frame r, the conical ends of the said stud and screw engaging with said indentations, thus forming a pivoted bearing for the block, allowing the same to conform to the longitudinal contour of the glass. The surfaces of these blocks are plain and curved to fit the contour of the glass to be ornamented, and they are used in forming the wide band, as shown at at, Fig. 7. For forming the irregular line (shown in Fig. 8) I use another form of tool and holder. The holder consists of a block having a series of forwardly-extending fingers and a reduced rear extension slotted at s. The markers or tools are carried by the rectangular frames u, the tool extending through the space between the fingers and projecting out from the top and bottom of the frame. These frames are adjustable to and from each other, and are held rigidly by thumb-nuts, the bolt u passing through the slot 5 and the spring-arm, thus holding the two together. In place of these frames a block i (see Fig. 3) may be secured to the end of the arms P. A slit is made in the block and the thin blade 25 inserted therein. This blade is used in forming the line 00, Fig. '7, and is preferably of thin steel about asixteenth of an inch by a quarter of an inch wide and three inches long.

It will be understood that each side of the machine is provided with a similar mechanism for holding the spring-arms carrying the engraving-tool, and in some cases two arms may be put 011 the same side. This is desirable in ornamenting the glass, as shown in Fig. 7. In this case the plates S are disconneetedv from the reciprocating rods and remain stationary. One of the plates carries two spring-arms, and these arms carry the tools If for forming the line :20. The opposite plate carries a single arm and the markingblock is carriedon the end of this arm. This block rests upon the glass between the tools If and forms the part 00.

In operation the machine works as follows: The tumbler is inserted in the end of the chuck and the lever 1" released. The sprin force the collar 0 in place and clamp the tumbler firmly within the end of said chuck and draw the driving-pulley upon the enlarged part of the shaft to drive the same. The rubbing or engraving blocks are now brought to bear upon the glass, the springarms supplying the frictional contact necessary. The beveled gear 2 is rotated by the rotation of the shaft 1) and transfers motion through the series of beveled gears to the disks 8. This reciprocates the rods 7L and the plates L, secured on the end thereof, thus reciprocating the arms P and the engravingblocks carried thereby. 'hen forming the straight line, as shown in Fig. '7, the rod 71/ is disconnected from the plate L, thus allowing the same to remain stationary during the rotation of the chuck and the tumbler carried thereby. The glass is rotated during the reciprocating of the engraving-blocks, said blocks reciprocating more rapidly than the shaft 1) rotates. The length of stroke of the rod 9 can be adjusted by moving the eccentric-pin nearer to or farther from the center of the disk. Sand is fed under the rubbingblocks during their operation, the tub a being provided to catch the waste. To remove the glass, the lever is forced to the left, drawing the collar 0' back against the pressure of the springs y and allowing the end of the chuck to be expanded and the glass removed. A collar 'L is secured on the shaft Z) to act as a stop against the end of the collar 0. The pulley b is moved when said lever is reversed onto the tapered part of the shaft by the disk b and revolves freely thereon, allowing the shaft to remain stationary.

The engraving is accomplished by means of sand applied either by hand from a tank below or from a tank overhead or by a feeding-up machine, as is found most desirable.
